Dynasylan® 1505

Dynasylan® 1505 is a bifunctional organic compound in which the silicon-functional ethoxy-groups hydrolyze in the presence of water to form reactive silanols, which can be bonded to an inorganic substrate; the organophilic amino group can interact with a suitable polymer.
Examples of suitable inorganic substrates are:
sand, mineral wool, silicic acid, quartz, cristobalit, wollastonite and mica; also suitable are aluminium hydroxide, kaolin, other silicate fillers, metal oxides and metals.
Examples of suitable polymers are:
phenolic resins, furan resins, silicones and melamie resin. Dynasylan® 1505 can undergo reactions with ketones or esters.
Silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates or carbamates.

Typical Applications

Dynasylan® 1505 is an important additive in many applications. For example it can be used as an additive in cold-curing phenolic and furan foundry resins to improve the flexural strength of sand/resin elements with very long shelf life of the resins.
Further examples are:
  • use in glass and metal primers
  • as an additive to phenolic resin binders used in abrasives manufacture
  • for treatment of inorganic fillers and pigments for use in mineral-filled composites or plastics or polymers
  • as an additive for the synthesis of organically modified silicones.

Benefits at a glance

The most important effects which can be achieved by using Dynasylan® 1505 are:
- improvement in product properties, such as mechanical properties, for example flexural strength, tensile strength, impact strength and modulus of elasticity or adhesion
- improvement in processing properties, such as viscosity
- moisture and corrosion resistance.
